Utilize the safest method possible for removing while protecting existing finished materials. 3.3 POLLUTION CONTROLS A. Remove and transport debris in a manner that will prevent spillage on adjacent surfaces and areas. B. Clean adjacent structures and improvements of dust, dirt, and debris caused by selective demolition operations. Return adjacent areas to condition existing before start of selective demolition. 3.4 SELECTIVE DEMOLITION A. Demolish and remove existing construction only to the extent required by new construction and as indicated on drawings. Use methods required to complete work within limitations of governing regulations and as follows: 1. Proceed with selective demolition systematically in area as scheduled. 2. Mark interface surfaces as required to enable workmen to identify items to be removed and items to be left in place intact. 3. Neatly cut openings and holes plumb, square, and true to dimensions required. Use cutting methods least likely to damage construction to remain or adjoining construction. To minimize disturbance of adjacent surfaces, use hand or small

24 power tools designed for sawing or grinding, not hammering and chopping. Temporarily cover openings to remain. 4. Cut or drill from the exposed or finished side into concealed surfaces to avoid marring existing finished surfaces. 5. Do not use cutting torches. 6. Return elements of construction and surfaces to remain to condition existing before start of selective demolition operations. 7. Do not cut any building structure without written authorization of the Architect. Any structural members accidentally or intentionally cut without proper authorization shall be restored to their original integrity and condition. 3.5 PATCHING AND REPAIRS A. Promptly patch and repair holes and damaged surfaces caused to adjacent construction by selective demolition operations. B. Where repairs to existing surfaces are required, patch to produce surfaces suitable for new materials. 1. Completely fill holes and depressions in existing walls to remain with an approved patching material, applied according to manufacturer s printed recommendations. C. Restore exposed finishes of patched areas and extend finish restoration into adjoining construction to remain in a manner that eliminates evidence of patching and refinishing. D. Use repair materials identical to existing materials. 1. Where identical materials are unavailable or cannot be used for exposed surfaces, use materials that visually match existing adjacent surfaces to the fullest extent possible. 2. Use materials whose installed performance equals or surpasses that of existing materials. 3.6 DISPOSAL OF DEMOLISHED MATERIALS A. General: Promptly dispose of demolished materials. Do not allow demolished materials to accumulate on-site. B. Debris to be hauled off. Coordinate with the Owner the debris-hauling route. C. Disposal: Transport demolished materials off Owner s property and legally dispose of them. 3.7 CLEANING A. Sweep the area affected by demolition and the debris-hauling route broom clean on completion of selective demolition operation. END OF SECTION

25 SECTION CONCRETE BEAM & COLUMN REPAIRS (BY UNF STRUCTURAL ENGINEER) October 28, 2016 Mr. Stephen B. Fagan, BA, Arch., MAOM Assistant Director Physical Facilities 1 UNF Drive Jacksonville, Florida RE: UNF Founders Hall, (Building 2), Jacksonville, FL Investigation of concrete beam and column spall G.M. Hill Engineering Project Dear Mr. Fagan; At your request a registered engineer from this office visited the above referenced building on September 30, The purpose of the visit was to make visual observations of the existing structural conditions to allow us to render an opinion regarding a cracks and spalls in the 2 nd floor beams and column at the north-west corner of building 2. Building 2 is a two-story building approximately 140 feet by 140 feet. The structure for the building consists of a concrete frame with infill brick walls. The 2 nd floor and roof are pre-cast concrete double-tee slabs. The original building was constructed around 1973 with a later addition to the southwest corner. Information on the existing structure was obtained from a set of As-Built drawings prepared by Reynolds Smith and Hills. Observations At the north-west corner of building 2, there is spalling and cracking in the corner of the 2 nd floor beam on both the west and north faces. There are diagonal cracks in the column at both the west and north faces that run from the top and bottom of the beam. The crack in the column below the 2 nd floor runs from the bottom of the beam to the top of a concrete cap beam cast over the top of the infill brick wall. The cracks in the beam and column have been previously caulked. (See Pictures 1, 2, 3 and 4). The area on the corner of the beam was sounded with a hammer and evidenced an unsound condition. The verticality of the column was checked with a 4 foot bubble level. The bottom of the column, up to the level of the concrete cap beam at the top of the first floor brick wall was found to be vertically plumb in both the northsouth and east-west directions. The north face of the column from about the level of the concrete cap beam up to the bottom of the 2 nd floor beam is deflected toward the south approximately ½. (See picture 5). Building 1 is of similar age and construction to building 2. The south-west corner of building 1 has cracking in the beam and column similar, to that observed in building 2. (See picture 6)

26 Conclusions The concrete spalling and cracking in the beam and column are the result of thermal and moisture induced movement of the 2 nd floor slab. The column is restrained by the concrete cap beam at the top of the brick wall and the movement caused internal stresses that lead to the cracking of the column and beam. The cracks do not appear to be recent, and may have been caused by the initial curing and loss of moisture in the 2 nd floor slab shortly after construction. The west exposure of the wall is most likely a contributing factor as well. Recommendations The concrete spall and cracks in the beam should be repaired by chipping out the un-sound concrete and repairing with an approved concrete repair product such as SIKA Sikacrete 211 SCC PLUS, polymer-modified selfconsolidating concrete with corrosion inhibitor. The repair procedure should be per the manufacturer s recommendations. The cracks in the columns may be repaired by epoxy injection utilizing SIKA Sikadur 33 epoxy paste for sealing the cracks and injection ports and Sikadur 35 Hi-Mod LV epoxy injection. Follow the manufacturer s recommended repair procedure for specific instructions. Our review is limited to the specific area addressed in this report. Please see the following page for photos of the areas inspected. No analysis was done of the existing structure. This report does not cover architectural, mechanical, electrical, life safety or hidden items. It has been a pleasure being of service to you in this matter. If you have any questions or need additional information, please do not hesitate to contact this office. Very Truly Yours G.M. Hill Engineering, Inc. Jeffrey D. McGee, P.E.
